If a user is asking to purchase some pairs, and you have one for LA, can you post a link to it, or is it not allowed?
If someone is looking for ponies in the Buy forum (edit: That your ponies meet the description of, of course.) or has PMed you to inquire about possibly buying a pony that is on auction, you may link them to the auction.
You just can't randomly post a thread to advertise the auction, spam unrelated threads with links, or randomly PM people who have not expressed interest or possible interest in the ponies..
That first part was exactly what I was asking. Thank you
